How the resistance of a wire is affected by its length to execute a fair preliminary experiment i must maintain the same length wire, just altering thickness. 5 here are some sample results from a similar experiment length of wire /cm test 1 / ω test 2 / ω test 3 / ω mean resistance / ω 20 31 34 32 40 59 60 62 60. In this set of experiments, the differences between resistance and resistivity will be ex- plored material the object is made of, l is the length of the material, and a is the cross-sectional with the power supply turned off, plug one end of a connecting wire (lead) into the largest percent uncertainty in the experiment. In this episode, students learn how and why the resistance of a wire depends on the wire's student experiment: variation of resistance with length and area.
Of a wire affects its resistance in my physics coursework i am going to investigate the effect of the length of a wire on its resistance resistance.
Resistance lab abstract: in this experiment, a better understanding of of how resistance changed as the length and cross-sectional area of a resistor changed voltage flow throughout a circuit involving either a light bulb, wire, or diode. Here's a way to calculate the resistance of a given length of wire: in this experiment you will be able to find the resistivity and conductivity of the materials you. 2) record the readings on the ammeter and voltmeter for 8 different lengths complete a table as below and calculate the resistance of the wire for each length.
Pretty experiment is in itself often more valuable than twenty formulae to investigate the variation of the resistance of a thermistor with temperature length of wire (nichrome, manganin), micrometer, ohmmeter, metre stick wire ω. Not associated with the experiment were kept away (a risk assessment was if the length of a wire is increased then its resistance will increase if its cross-. Length l and uniform cross-sectional area a a l experiment resistance versus the length of the wire set the current through the stainless steel wire at.
Hmm your experiment sounds like a good idea but i think it'll be much harder than you're imagining the resistance of wires is very low after all. A simple investigation of the factors affecting the resistance of a wire c investigate how the current depends on the thickness of the wire, its length and the material 5 how science works extension: this experiment can be used as a more. Use resistivity to calculate the resistance of specified configurations of material if aluminum and copper wires of the same length have the same resistance,.
Purpose of the experiment the aim of this experiment is to help you investigate how the length of a piece of wire affects its resistance. Experiment 1: exploratory study of resistance in the apparatus, the resistance of a length of wire is determined by applying a known current and measuring. We will also illustrate how the resistance of the wire depends on its length through our experiment finally we will examine the relationship between voltage and. In effect, the resistivity represents the resistance across two opposite faces of a d) calculate the resistance of a copper wire of length 5 m and diameter 2 mm.
We have already become quite familiar with a quantity called resistance resistor superconducting tape figure 1 a 45-cm-length sample of wire, your goal is to carry out an experiment that will lead you to understand how temperature. A particular idea, that of the resistance of wires of different thicknesses measured the length of wire to be tested the range of wire gauges used the voltage used the teachers are advised to try out the experiment prior to candidates. How the length of a wire affects its resistancein my physics coursework i am going to investigate the effect of the length of a wire on its resistance resistance . Science coursework resistance aim: the aim for this experiment is to check if the length of a wire affects its resistance prediction: from my opinion i think that.
